This 6.1mm 5MP M12 low distortion lens is designed for compact camera systems that require controlled image geometry and a moderately focused field of view. With a 1/2.5″ image format and distortion below 1%, it delivers clear 5MP imaging while minimizing geometric deformation across the image.
Featuring an M12×0.5 mount, F3.0 fixed aperture, 0.2m minimum object distance, and a compact 2G2P optical structure, this fixed focal lens is well suited to embedded cameras, smart monitoring modules, compact inspection devices, and space-constrained vision systems.
This 6.1mm M12 low distortion lens is designed for imaging systems where the camera needs to maintain a relatively focused view while keeping geometric distortion under tight control. Its 50° horizontal FOV provides a balanced coverage area without the excessive scene expansion associated with short-focal-length wide-angle optics.
The lens is particularly suitable for compact inspection cameras, smart access devices, embedded monitoring modules, equipment-mounted cameras, and fixed-position visual sensing systems. The distortion below 1% helps preserve the relative shape and position of objects, which can be beneficial when the captured images are used for visual analysis rather than simple scene observation.
The 0.2m minimum object distance also makes this lens suitable for near-to-medium distance imaging. It can be installed close to equipment, access points, work surfaces, or monitored objects while maintaining a practical field of view. This makes the lens a useful option for compact systems where the camera cannot be positioned far away from the target.
The M12×0.5 interface further supports integration into small camera housings and embedded vision modules. Engineers evaluating the relationship between sensor size, focal length, and field coverage can refer to Towin’s Sensor Guide and Lens Selection Guide.
For engineers comparing different M12 optical configurations, Towin’s M12 Lenses category provides additional lens options with different focal lengths and optical characteristics. The FOV Calculator can also help estimate the expected scene coverage for a specific camera and working distance.

Designed for compact inspection, embedded monitoring, and low-distortion visual sensing applications.
Q: What type of lens is this 6.1mm M12 lens?
A: It is a fixed focal, low distortion M12 lens designed for 1/2.5″ image sensors and 5MP imaging. Its distortion is specified below 1%.
Q: Is this 6.1mm M12 lens a wide-angle lens?
A: No. Its diagonal FOV is 60° and horizontal FOV is 50°, which provides a moderate field of view rather than the broad coverage normally associated with wide-angle M12 lenses.
Q: What sensor format does this lens support?
A: The specified image format is 1/2.5″, with a resolution rating of 5MP.
Q: What is the field of view of the 6.1mm lens?
A: The lens provides a 60° diagonal FOV, 50° horizontal FOV, and 38° vertical FOV.
Q: What is the advantage of less than 1% distortion?
A: Distortion below 1% helps reduce geometric deformation and provides a more consistent representation of objects across the image. This can be useful for inspection, measurement-related imaging, and visual analysis.
Q: What is the minimum object distance of this M12 lens?
A: The minimum object distance is 0.2m, allowing the lens to capture relatively close subjects while maintaining its specified imaging characteristics.
Q: What does the 2G2P optical structure mean?
A: 2G2P indicates an optical construction using two glass elements and two plastic elements. This type of construction can support a compact and lightweight lens design for embedded camera applications.
Q: How can I determine whether the 6.1mm focal length is suitable for my camera?
A: The appropriate focal length depends on sensor format, working distance, target size, and required field of view. Towin’s Focal Length Calculator can help estimate the focal length needed for a specific imaging setup.
